To all whom t may concern:

Be it known that I, TIMOTHY. MULLowand I do herebydeclare thatthe/following is a full7 clear, and eXact'descri tionthereof. Y

Thus the base member as a wholercomprises anelbow .and theinner: or distributingv arm 2.ofsaid a base;section.iwliich at its pointof intersec- 'tion==,=with1 the.` leg hasli'secured vthereto aloopedwtie-rod 6, one stretch. 6 of which tierod extends: obliquelydownward iand is securedl to the foot 3. by a retaining fboltt the samealsojserving to confine the spar sustaining: chair-iron heopposite-stretch loop for coupling..l connection with an`foblioluelydisposed truss-rod 8,- the same betheleg'Sand-foot 3. is anangle-iron trans- 'versely-disposed heelV bar 9, to the ends tofwhichareadjustably secured toev strips 10, the adjustmentY of thefsamebeing eected by .'heelrfbolts 10-.1which are arranged :to engage any oneof aseries of apertures in the toe-y strips. Theouteriendszof the toestrips v-10 are in turn securedito ends of across-arm 11, which latteris secured to the footf by a :retaining bolt 12 that -is selectivelyfitted into any oneof-a series of'bolt apertures 12 Aformed in thehorizontally disposed webtof Vthe `footV 3', whereby the toe-strips maybe adjusted and secured forwardly` or backwardly and, owing tothisadjnstable connec- `tion each toe-strip can be; independentlyshifted Yback and forth. i: By the adjustable arrangement just describedthe inner ends of the toe strips 10 may be arrangedto abut and conformto the circular contour of the silo whereby they serve .toresist loadstrainpupon theend-of. the spar:arm, as lclearly shown in Fig. 2.

, In order to; firmly vclampthe derrickspar arm l to windows havingsills varying in width, I provide an adjustable sill-'clamping foot, 13,which foot is secured lto a clip bracket 14, ythatis slidablymountedupon the inwardly projecting distributerarm 2.
